Hi All, I did an unintentional upgrade of Jenkins from version 1.532.3 to 1.565.3 using the Long Term Support rpm's from jenkins.org. I tried to correct the situation by downgrading to 1.532.1.
After the downgrade matrix-auth errors are written to jenkins.log : WARNING: Failed to scout hudson.security.GlobalMatrixAuthorizationStrategy$PermissionAdderImpl java.lang.InstantiationException: /opt/jenkins/data/plugins/matrix-auth/WEB-INF/lib/classes.jar might need to be rebuilt: java.lang.ClassNotFoundException: hudson.security.GlobalMatrixAuthorizationStrategy$PermissionAdderImpl at net.java.sezpoz.IndexItem.element(IndexItem.java:144) ... It's no longer possible to log in to Jenkins, it just dumps : java.lang.NullPointerException at hudson.security.HudsonPrivateSecurityRealm$4.isPasswordValid(HudsonPrivateSecurityRealm.java:670) at hudson.security.HudsonPrivateSecurityRealm$Details.isPasswordCorrect(HudsonPrivateSecurityRealm.java:479) at hudson.security.HudsonPrivateSecurityRealm.authenticate(HudsonPrivateSecurityRealm.java:178) ... I then disabled all security by modifying config.xml, setting useSecurity to false and removing the authorizationStrategy and securityRealm tags. That got things going again, but I of course want to recover cleanly. I don't have a lot experience with Jenkins so I am not sure what to try next. The Jenkins wiki mentiones that matrix-auth was split of from the Jenkins core, but the only rpm we ever used is the one I mentioned above. Any suggestions? Regards, Willem. P.S. Upgrading Jenkins is not an option at this time. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
